ANATOMY IN A NUTSHELL. 



noidal fissure (anterior lacerated) into the cavernous sinus which divides into 

 superior and inferior petrosal sinuses, each of which empties into the lateral 

 sinus. The lateral sinus and inferior petrosal sinus form the internal jugular 

 vein. This vein receives the subclavian vein thus forming the innominate vein. 

 The two innominate veins form the superior vena cava which empties into the 

 righl auricle of the heart. Thus the blood passes from the eye-ball to the heart.

The arterial blood passes from the heart to the eye-ball as follows: 

 From ili<' lefl ventricle through the arch of the aorta through which it 

 passes in'" the common carotid on the right side it must first go through the 

 innominate artery— from the common carotid into the internal carotid by 

 means of which it which passes into the skull through the carotid canal and' 

 middle lacerated foramen. Then the internal carotid gives off the ophthalmic
